Feedbackflowhq uses Brevo for marketing email and Amazon SES for transactional/notifications. Email goes out from 2 different subdomains. Their email authentication setup is good (score 73/100). Missing: DMARC enforcement.
Amazon SESAuthentication signals observed in this brand's emails. SPF, DKIM and DMARC are the standard sender-authentication stack — see the DMARC policy below for whether spoofing is actually blocked or just monitored. One-click unsubscribe meets Google & Yahoo's bulk-sender requirements.
DMARC reports sent to brevo.com. Policy
p=none is monitor-only — receivers won't act on spoofing yet.
SPF alignment: 50% of observed emails use an aligned return-path (send.mail.feedbackflowhq.com); the rest use third-party paths (af.d.mailin.fr) where DMARC has to rely on DKIM alignment.
DKIM alignment: all 1 observed email sign with a domain aligned with feedbackflowhq.com (mail.feedbackflowhq.com). DKIM authenticates the visible From — supports DMARC directly.
Brands often use multiple ESPs (e.g. one for marketing, another for transactional/notifications).

Which ESP's emails are landing where. Sorted by spam % so problem senders surface first. Brands using one ESP for marketing and another for transactional often see very different placement profiles per ESP. Per-ESP folder data only started being captured recently — counts here may be smaller than the total above until backfill catches up.
| ESP | Emails | Placement | Inbox % | Tabs % | Spam % |
|---|---|---|---|---|---|
| Brevo | 1 | 100.0% | 0.0% | 0.0% | |
| Amazon SES | 1 | 100.0% | 0.0% | 0.0% |
Daily observations per ESP. Brands often run multiple ESPs concurrently — marketing on one, transactional on another — so this chart shows usage rather than switches.
